  • Patent number: 6366556
    Abstract: Methods and apparatus are disclosed for providing virtual rings in SONET networks. By using an unused byte in the SONET path overhead, in conjunction with multiframe operation, restoration is performed at the sub-network connection layer or path layer to provide a finer granularity of protection which provides more efficient use of bandwidth. By restoring the operation of the SONET path overhead before exiting a virtual ring created using the present invention, the present virtual ring can be applied to the existing SONET network. Since a virtual ring provides restoration at a path level, a virtual ring can be comprised of various SONET rate interfaces. Further, restoration circuits are not dedicated, but are shared to create virtual rings as needed, which increases bandwidth efficiency and which are automatically and quickly created without the need for a centralized controller.
